उत्तर
Elevation in boiling point is a colligative property, as it depends on the number of solute particles present in a solution.

The boiling point to a solution containing 50 gm of a non-volatile solute in 1 kg of solvent is 0.5° higher than that of pure solvent. Determine the molecular mass of the solute (give molecular mass of solvent) = 78 g mol–1 and kb for solvent = 2.53 km–1)
Assertion (A): Elevation in boiling point is a colligative property.
Reason (R): The lowering of vapour pressure of solution causes elevation in boiling point.
Calculate the boiling point elevation for a solution prepared by adding 10 g of MgCl2 to 200 g of water, assuming MgCl2 is completely dissociated.
(Kb for Water = 0.512 K kg mol−1, Molar mass MgCl2 = 95 g mol−1)
